본 발명은 입체물 스캐너에 관한 것으로서, 보다 구체적으로는 신발 제조를 위해 사람의 발 형상을 스캐닝하는 스캐너에 관한 것이다.The present invention relates to a three-dimensional scanner, and more particularly to a scanner for scanning the shape of a person's foot for shoe manufacturing.

일반적으로, 스캐너는 문서나 그림 등이 재치되는 평면 유리판 하부에 CCD 카메라와 광원이 설치된 구조로 이루어져 있다. 이러한 스캐너는 CCD 카메라가 수평 이동하는 것에 의해, 문서나 그림을 스캐닝하게 된다. 상기와 같은 2차원형 스캐너에 대한 기술의 진보로, 레이저를 이용해서 입체물을 스캐닝하는 3차원형 스캐너가 개발되어 여러 분야에 응용되도록 다각도의 연구가 진행되고 있는 실정이다.In general, a scanner has a structure in which a CCD camera and a light source are installed under a flat glass plate on which documents or pictures are placed. Such a scanner scans a document or a picture by moving the CCD camera horizontally. As the technology of the two-dimensional scanner as described above, a three-dimensional scanner that scans a three-dimensional object using a laser has been developed and the research of various angles to be applied to various fields.

이러한 연구 개발에 부응하여, 본원인은 2000년 4월 24일자에 3차원 스캐너에 관한 특허출원(출원번호:2000-21744호)을 하였다. 도 1 및 도 2는 상기 스캐너를 도시한 것으로서, 도 1은 스캐너의 외관을 나타낸 사시도이고, 도 2는 내부 구조를 나타낸 사시도이다.In response to this research and development, the applicant filed a patent application (Application No. 2000-21744) on the three-dimensional scanner on April 24, 2000. 1 and 2 show the scanner, FIG. 1 is a perspective view showing the appearance of the scanner, and FIG. 2 is a perspective view showing the internal structure.

도 1에 도시된 바와 같이, 스캐너는 전면과 상면에 개구부(2)가 형성된 스캐너 몸체(1)와, 스캐너 몸체(1)의 내부에 설치되어 입체물이 재치되는 투명 재치대(15)와, 상면 개구부의 양측 경계에 힌지(4)로 연결되고 통공부(5)가 형성된 한 쌍의 덮개판(3)을 포함한다. 개구부(2)의 양측벽 구조를 이루는 부분에는 윈도우(19)가 형성된 칸막이(18)가 설치되어 있다.As shown in FIG. 1, the scanner includes a scanner body 1 having anopening 2 formed on a front surface and an upper surface thereof, a transparent mounting table 15 installed inside the scanner body 1 to mount a three-dimensional object, and an upper surface thereof. It comprises a pair ofcover plates 3 connected to hinges on both sides of the opening and formed with a throughsection 5. Thepartition 18 in which thewindow 19 was formed is provided in the part which comprises the both side wall structure of theopening part 2. As shown in FIG.

도 2에는 스캐너의 내부 구조가 사시도로 도시되어 있다. 도시된 바와 같이, 스캐너 몸체(1)의 내부에 슬라이더(11)가 수평 이동이 가능하게 지지되어 있다. 투 명 재치대(15)는 슬라이더(11)의 내부 중간에 수평하게 설치되어, 슬라이더(11)와 함께 수평 이동하도록 되어 있다. 슬라이더(11)의 양측 내벽 상하부 각각에 한 쌍의 카메라(13a,13b)가 설치되어 있다. 즉, 총 카메라의 수는 4개이다. 상부 카메라(13a)의 측부에 투명 재치대(15)로 레이저를 조사하는 레이저 조사기(12)가 설치되어 있다.2 shows a perspective view of the internal structure of the scanner. As shown, theslider 11 is supported inside the scanner body 1 so that horizontal movement is possible. The transparent placing table 15 is provided horizontally in the middle of theslider 11 so as to move horizontally with theslider 11. A pair ofcameras 13a and 13b are provided on the upper and lower portions of both inner walls of theslider 11, respectively. In other words, the total number of cameras is four. Thelaser irradiator 12 which irradiates a laser with thetransparent mounting base 15 is provided in the side part of the upper camera 13a.

특히, 각 카메라(13a,13b)는 투명 재치대(15)를 촬영해야 하므로, 상부 카메라(13a)는 하부를 향해 경사지게 배치되고, 하부 카메라(13b)는 상부를 향해 경사지게 배치되어 있다. 또한, 레이저 조사기(12)도 하부를 향해 경사지게 배치되어 있다.In particular, since eachcamera 13a, 13b should photograph thetransparent mounting base 15, the upper camera 13a is inclined toward the lower part, and thelower camera 13b is inclined toward the upper part. In addition, thelaser irradiator 12 is also inclined toward the lower side.

상기와 같이 구성되어서, 입체물, 한 예로 발을 투명 재치대(15)에 올려놓고 양측 덮개판(3)을 덮으면, 다리 부분은 합쳐진 통공부(5)를 통해 노출된다. 이러한 상태에서, 슬라이더(11)가 수평 이동하면서 윈도우(19)를 통해 양측 레이저(12)로부터 발을 향해 레이저가 조사되고, 이를 4개의 카메라(13a,13b)가 촬영하게 된다. 이러한 동작에 의해, 발의 3차원 형상이 스캐닝되고, 얻어진 3차원 데이터를 이용해서 신발 제작에 응용할 수가 있게 된다.When the three-dimensional object, for example, the foot is placed on the transparent mounting table 15 and the bothcover plates 3 are covered, the leg portion is exposed through the combined throughhole 5. In this state, the laser is irradiated toward the feet from bothlasers 12 through thewindow 19 while theslider 11 is horizontally moved, and the fourcameras 13a and 13b are photographed. By this operation, the three-dimensional shape of the foot is scanned, and the three-dimensional data obtained can be used to make shoes.

그런데, 본원인이 선출원한 상기 스캐너는 입체물의 3차원 형상을 정확하게 스캐닝하는데는 큰 무리가 없지만, 다음과 같은 부수적인 단점들을 안고 있다.By the way, the scanner, which the applicant has filed in advance, has no great difficulty in accurately scanning the three-dimensional shape of the three-dimensional object, but has the following additional disadvantages.

우선, 덮개판(3)이 상부에만 덮혀지게 되므로 전면 개구부(2)는 노출된 상태가 된다. 이로 인하여, 스캐닝 동작 중에 외부의 빛과 같은 인자들에 의해 스캐닝된 화상에 노이즈가 발생되었다.First, since thecover plate 3 is covered only on the upper portion, thefront opening 2 is exposed. As a result, noise was generated in the scanned image by factors such as external light during the scanning operation.                        

또한, 양측 상하부 카메라(13a,13b)는 슬라이더(11)의 이동 방향과 직교하는 방향으로 배치되어 있기 때문에, 발의 전단과 후단 부분을 정확하게 촬영하기가 곤란하였다.In addition, since the upper andlower cameras 13a and 13b are arranged in a direction orthogonal to the moving direction of theslider 11, it is difficult to accurately photograph the front and rear ends of the foot.

아울러, 하부 카메라(13b)는 투명 재치대(15)의 하부에 배치되어 있는 관계로, 하부 카메라(13b)의 수용 공간만큼 스캐너의 높이가 높아지는 문제점이 있다. 스캐너의 크기가 커지면, 우선 취급이 곤란하고 운반하는데도 장애가 있다.In addition, since thelower camera 13b is disposed below the transparent mounting table 15, there is a problem in that the height of the scanner increases as much as the accommodation space of thelower camera 13b. As the size of the scanner becomes larger, it is difficult to handle first and there is an obstacle in carrying.

본 발명은 본원인의 선발명을 개선한 것으로서, 외부 노이즈를 완전 차단할 수 있는 입체물 스캐너를 제공하는데 목적이 있다.An object of the present invention is to provide a three-dimensional scanner capable of completely blocking external noise as an improvement of the applicant's selection.

본 발명의 다른 목적은, 입체물의 전단과 후단도 정확하게 촬영할 수 있게 하는데 목적이 있다.Another object of the present invention is to make it possible to accurately photograph the front end and the rear end of a three-dimensional object.

본 발명의 또 다른 목적은, 하부 카메라의 위치로 인해서 스캐너의 높이가 높아지는 것을 방지하는데 있다.Another object of the present invention is to prevent the height of the scanner from increasing due to the position of the lower camera.

상술한 본 발명의 목적을 달성하기 위하여, 본 발명에 따른 스캐너는 상부면이 개구된 스캐너 몸체를 포함한다. 스캐너 몸체의 개구부에 한 쌍의 덮개판이 슬라이드식으로 설치된다. 각 덮개판의 경계면에 입체물의 통과를 위한 통과홈이 각각 형성된다. 통과홈을 통해 입체물이 재치되는 투명 재치대가 스캐너 몸체의 내부에 수평하게 설치된다. 투명 재치대의 하부에 입체물이 투영되는 투영경이 배치된다. 투영경은 수평 이동 장치에 의해 수평 이동된다. 투영경의 이동 방향과 직교하 는 양측에 브래킷이 설치된다. 양측 브래킷에 입체물을 직접 촬영하는 적어도 하나의 상부 카메라와, 투영경에 투영된 화상을 촬영하는 적어도 하나의 하부 카메라가 설치된다. 특히, 하부 카메라는 투영경의 상부에 배치되어, 투영경을 향하도록 하부를 향하게 된다. 아울러, 상하부 카메라는 2대씩으로 구성되고, 각 카메라는 안쪽을 향해 경사지게 배치된다.In order to achieve the above object of the present invention, the scanner according to the present invention includes a scanner body having an upper surface opened. A pair of cover plates is slidably installed in the opening of the scanner body. Passing grooves for passing the three-dimensional object are respectively formed in the boundary surface of each cover plate. A transparent mounting table on which the three-dimensional object is placed through the through groove is horizontally installed inside the scanner body. The projection mirror in which the three-dimensional object is projected is disposed under the transparent mounting table. The projection mirror is horizontally moved by the horizontal moving device. Brackets are installed on both sides perpendicular to the direction of movement of the projection mirror. At least one upper camera for directly photographing a three-dimensional object and at least one lower camera for photographing an image projected on the projection mirror are installed on both brackets. In particular, the lower camera is disposed above the projection mirror and faces downward to face the projection mirror. In addition, the upper and lower cameras are composed of two, each camera is disposed inclined inward.

또한, 슬라이드의 양측부 각각에 투명 재치대에 재치된 입체물로 레이저를 조사하는 레이저 조사기가 설치된다. 각 카메라의 촬영을 위해, 스캐너 몸체 내부에는 램프가 구비된다.In addition, laser irradiation machines for irradiating a laser with a three-dimensional object placed on a transparent mounting table are provided on each side of the slide. For shooting each camera, a lamp is provided inside the scanner body.

상기된 본 발명의 구성에 의하면, 스캐닝 동작이 덮개판으로 완전 차단된 스캐너 몸체 내부에서 수행되므로, 외부 노이즈로 인한 영상 왜곡을 방지할 수가 있다. 또한, 각 카메라가 입체물을 직접 촬영하지 않고 투영경에 투영된 화상을 촬영하게 되므로, 하부 카메라를 투영경 상부에 배치할 수가 있게 되어, 스캐너의 높이가 하부 카메라로 인해 높아지는 것도 방지할 수가 있게 된다. 특히, 각 카메라는 안쪽을 향해 경사지게 배치되므로써, 입체물의 전후단을 정확하게 촬영할 수가 있게 된다.According to the configuration of the present invention described above, since the scanning operation is performed inside the scanner body completely blocked by the cover plate, it is possible to prevent image distortion due to external noise. In addition, since each camera captures an image projected onto the projection mirror without directly photographing a three-dimensional object, the lower camera can be disposed above the projection mirror, thereby preventing the height of the scanner from being increased due to the lower camera. . In particular, since each camera is inclined inwardly, it is possible to accurately photograph the front and rear ends of the three-dimensional object.

이하, 본 발명의 바람직한 실시예에 따른 입체물 스캐너를 도면들을 참조하여 상세하게 설명한다.Hereinafter, a three-dimensional object scanner according to a preferred embodiment of the present invention will be described in detail with reference to the drawings.

도 3은 본 발명에 따른 스캐너의 외관을 나타낸 사시도이고, 도 4는 도 3의 스캐너에서 외장을 제거하여 스캐너의 내부 구조를 나타낸 평면도이며, 도 5는 각 구성요소들의 배치 관계를 명확하게 나타내기 위한 스캐너의 정단면도이다.Figure 3 is a perspective view showing the appearance of the scanner according to the present invention, Figure 4 is a plan view showing the internal structure of the scanner by removing the exterior of the scanner of Figure 3, Figure 5 clearly shows the arrangement relationship of each component Is a sectional front view of the scanner.                    

먼저, 도 3을 참조로, 스캐너는 대략 긴 장방형의 스캐너 몸체(20)를 포함한다. 스캐너 몸체(20)는 길이 방향을 따라 상부면에 직사각형 형태로 길게 형성된 개구부를 갖는다. 한 쌍의 덮개판(30,31)이 개구부에 슬라이드식으로 설치되어, 각 덮개판(30,31)이 맞대어지게 되면 스캐너 몸체(20)의 내부가 외부와 완전 차단된다. 한편, 입체물을 스캐너 몸체(20) 내부로 진입시킬 수 있도록 하기 위해서, 각 덮개판(30,31)의 경계면에 반호 형상의 통과홈(32,33)이 형성된다. 따라서, 각 덮개판(30,31)이 맞대어지게 되면, 각 통과홈(32,33)들은 합쳐져서 하나의 원 형상을 이루게 된다. 각 덮개판(30,31)은 모터와 같은 구동원으로 자동 개폐시키거나 또는 수동으로 개폐시킬 수 있을 것이다.First, referring to FIG. 3, the scanner includes ascanner body 20 of approximately long rectangle. Thescanner body 20 has an opening formed in a rectangular shape on the upper surface along the longitudinal direction. A pair ofcover plates 30 and 31 are slidably installed in the openings, and when thecover plates 30 and 31 face each other, the inside of thescanner body 20 is completely blocked from the outside. On the other hand, in order to be able to enter the three-dimensional object into thescanner body 20, semicircular arc-shaped through grooves (32, 33) are formed in the boundary surface of each cover plate (30, 31). Therefore, when thecover plates 30 and 31 are butted together, therespective pass grooves 32 and 33 are combined to form one circle shape. Eachcover plate 30, 31 may be opened or closed automatically or manually by a drive source such as a motor.

한편, 본 실시예에서는, 스캐너 몸체(20)와 덮개판(30,31)이 별도로 구성되는 것으로 예시하였으나, 반드시 별도 구성요소일 필요는 없다. 즉, 덮개판(30,31)을 생략하고, 대신에 스캐너 몸체(20)의 상부면에 발과 같은 입체물이 통과할 수 있을 정도 크기의 통과공이 형성될 수도 있다.In the present embodiment, thescanner body 20 and thecover plates 30 and 31 are illustrated as being separately configured, but need not necessarily be separate components. That is, thecover plates 30 and 31 may be omitted, and instead, a through hole having a size enough to allow a three-dimensional object such as a foot to pass may be formed on the upper surface of thescanner body 20.

도 4에 스캐너의 내부 구조가 상세하게 도시되어 있다. 도 4에 도시된 바와 같이, 각 통과홈(32,33)을 통해 스캐너 몸체(20) 내부로 진입한 입체물, 본 실시예에서는 사람의 발이 재치되는 투명 재치대(40)가 스캐너 몸체(20) 내부에 수평하게 배치된다. 투명 재치대(40)는 스캐너 몸체(20)의 저면과 소정 간격을 두고 배치된다.The internal structure of the scanner is shown in detail in FIG. 4. As shown in FIG. 4, the three-dimensional object entering the inside of thescanner body 20 through each of the throughholes 32 and 33, and in this embodiment, the transparent mounting table 40 on which the human foot is placed is thescanner body 20. It is arranged horizontally inside. The transparent mounting table 40 is disposed at a predetermined distance from the bottom of thescanner body 20.

입체물의 저부가 투영되는 투영경(50)이 투명 재치대(40)의 하부에 배치된다. 투영경(50)은 수평 이동 장치에 의해 덮개판(30,31)의 이동 방향을 따라 수평 이동하게 된다.Theprojection mirror 50 on which the bottom of the three-dimensional object is projected is disposed below the transparent mounting table 40. Theprojection mirror 50 is horizontally moved along the moving direction of thecover plates 30 and 31 by the horizontal moving device.

수평 이동 장치는 구동원인 모터(90)를 포함한다. 도 5에 상세하게 도시된 바와 같이, 모터(90)에 의해 정위치에서 회전되는 리드 스크류(91)가 투영경(50)의 밑면에 나사결합된다. 즉, 리드 스크류(91)는 덮개판(30,31)의 이동 방향을 따라 배치된다.The horizontal moving device includes amotor 90 as a drive source. As shown in detail in FIG. 5, alead screw 91 rotated in position by themotor 90 is screwed to the bottom surface of theprojection mirror 50. That is, thelead screw 91 is arrange | positioned along the moving direction of thecover plates 30 and 31. FIG.

2개의 브래킷(61,62)가투영경(50)의 양측, 즉 리드 스크류(91)의 축방향과 직교하는 방향인 투영경(50)의 양측에 설치된다. 브래킷(61,62)은 스캐너 몸체(20)의 양측벽을 따라 세워진 형상을 갖는다. 양측 브래킷(61,62)은 스캐너 몸체(20)의 저면에 설치된 가이드(63)로 이동 가능하게 지지된다.Twobrackets 61, 62 areprovided on both sides of theprojection mirror 50, that is, on both sides of theprojection mirror 50, which is a direction orthogonal to the axial direction of thelead screw 91. Thebrackets 61 and 62 have a shape erected along both side walls of thescanner body 20. Bothbrackets 61 and 62 are movably supported by theguide 63 installed on the bottom of thescanner body 20.

상부 카메라(71,72) 2대와 하부 카메라(73,74) 2대가 각 브래킷(61,62)에 설치된다. 브래킷(61,62)이 2개이므로, 총 카메라의 수는 8개가 된다. 양측 브래킷(61,62)에 배치된 각 카메라들의 배치 구조는 동일하므로, 어느 한 브래킷(61)에 배치된 카메라들의 배치 구조에 대해서만 설명한다.Twoupper cameras 71 and 72 and twolower cameras 73 and 74 are mounted to thebrackets 61 and 62. Since there are twobrackets 61 and 62, the total number of cameras is eight. Since the arrangement structure of each camera arranged in bothbrackets 61 and 62 is the same, only the arrangement structure of the cameras arranged in any one of thebrackets 61 will be described.

상부 카메라(71,72) 2대는 투명 재치대(40)에 재치된 입체물을 직접 촬영하는 것으로서, 브래킷(61)의 상부 양측에 배치된다. 따라서, 각 상부 카메라(71,72)는 투명 재치대(40)를 향하도록 하부를 향하게 되고, 특히 입체물의 전후단을 정밀하게 촬영할 수 있도록 안쪽으로 소정의 예각을 이루면서 경사지게 배치된다.The twoupper cameras 71 and 72 directly photograph the three-dimensional objects placed on the transparent mounting table 40, and are disposed on both sides of the upper portion of thebracket 61. Therefore, each of theupper cameras 71 and 72 faces downward to face the transparent mounting table 40, and is inclined at a predetermined acute angle inward so as to accurately photograph the front and rear ends of the three-dimensional object.

하부 카메라(73,74) 2대는 투영경(50)에 투영된 입체물의 저부를 촬영하는 것으로서, 브래킷(61)의 하부 양측에 배치된다. 각 하부 카메라(73,74)는 투영경(50)보다는 높으면서 투명 재치대(40)보다는 약간 아래인 위치에 배치된다. 각 하부 카메라(73,74)도 상부 카메라(71,72)와 마찬가지로, 하부를 향하면서 안쪽을 향해 경사지게 배치된다.Twolower cameras 73 and 74 photograph the bottom of the three-dimensional object projected onto theprojection mirror 50, and are disposed on both lower sides of thebracket 61. Eachlower camera 73, 74 is disposed at a position higher than theprojection mirror 50 and slightly below the transparent mounting table 40. Like theupper cameras 71 and 72, eachlower camera 73 and 74 is also arranged inclined inward while facing downward.

입체물로 레이저를 조사하는 2대의 레이저 조사기(81,82)가 양측 브래킷(61,62)의 상부 중앙에 설치된다. 물론, 각 레이저 조사기(81,82)에서 조사되는 레이저가 투명 재치대(40)를 향해야 하므로, 각 레이저 조사기(81,82)는 하부를 향하면서 경사지게 배치된다.Twolaser irradiators 81 and 82 for irradiating a laser with a three-dimensional object are installed in the upper center of bothbrackets 61 and 62. Of course, since the laser irradiated from each laser irradiator (81, 82) should face the transparent mounting table 40, each laser irradiator (81, 82) is disposed inclined while facing downward.

한편, 통과홈(32,33)이 사람의 발로 차단되면서 각 덮개판(30,31)이 닫히게 되면, 스캐너 몸체(20)의 내부는 어두워지게 된다. 이러한 상태에서는, 각 카메라(71,72,73,74)가 입체물을 촬영할 수가 없게 되므로, 램프(100)가 스캐너 몸체(20)의 내부 소정 위치에 배치된다. 본 실시예에서는, 램프(100)는 모터(90)의 상부에 배치된다.On the other hand, when each of thecover plates 30 and 31 is closed while the throughgrooves 32 and 33 are blocked by the human foot, the inside of thescanner body 20 becomes dark. In this state, since thecameras 71, 72, 73, and 74 cannot capture three-dimensional objects, thelamp 100 is disposed at a predetermined position inside thescanner body 20. In this embodiment, thelamp 100 is disposed above themotor 90.

상기와 같이 구성된 본 실시예에 따른 스캐너로 신발 제작을 위해 사람의 발을 스캐닝하는 동작을 상세히 설명한다.An operation of scanning a person's foot for shoe manufacturing with a scanner according to the present embodiment configured as described above will be described in detail.

2개의 덮개판(30,31)을 열은 상태에서, 발을 투명 재치대(40)상에 올려놓는다. 그런 다음, 덮개판(30,31)을 닫으면, 다리 부분이 각 덮개판(30,31)의 통과홈(32,33) 내주면에 밀착된다. 따라서, 스캐너 몸체(20)의 내부는 외부의 빛이 대부분 차단되는 공간이 된다.With the twocover plates 30 and 31 open, the feet are placed on the transparent mounting table 40. Then, when thecover plates 30 and 31 are closed, the leg portions are in close contact with the inner circumferential surfaces of thepassage grooves 32 and 33 of therespective cover plates 30 and 31. Therefore, the inside of thescanner body 20 becomes a space where most of the external light is blocked.

이러한 상태에서, 램프(100)를 점등한 후, 각 레이저 조사기(81,82)로부터 발을 향해 레이저가 양측으로부터 조사된다. 이와 동시에, 모터(90)를 가동시키면, 리드 스크류(91)의 회전에 의해 투영경(50)이 수평 이동하게 된다.In this state, after thelamp 100 is turned on, lasers are irradiated from both sides toward the feet from therespective laser irradiators 81 and 82. At the same time, when themotor 90 is operated, theprojection mirror 50 is horizontally moved by the rotation of thelead screw 91.                    

이러한 수평 이동에 의해 레이저가 발 전체를 조사하게 되는 것을, 상부 카메라(71,72) 2대가 발의 윗부분을 촬영하게 되고, 하부 카메라(73,74) 2대가 투영경(50)에 투영된 화상을 촬영하게 된다.This horizontal movement causes the laser to irradiate the entire foot. Twoupper cameras 71 and 72 photograph the upper part of the foot, and twolower cameras 73 and 74 project the image projected onto theprojection mirror 50. I will shoot.

이때, 상하부 각 카메라(71,72,73,74)는 안쪽으로 경사지게 배치되어 있으므로, 발의 전단과 후단에 대한 시야각이 확보되므로써, 발의 전단과 후단을 정확하게 촬영할 수가 있게 된다.At this time, since the upper andlower cameras 71, 72, 73, and 74 are inclined inward, the viewing angles for the front and rear ends of the foot are secured, so that the front and rear ends of the foot can be accurately photographed.

각 카메라(71,72,73,74)에서 촬영된 3차원 영상 데이터는 컴퓨터로 전송되어, 모니터상에 발 형상이 정확하게 디스플레이된다.The three-dimensional image data captured by thecameras 71, 72, 73, and 74 are transferred to a computer so that the shape of the foot is displayed accurately on the monitor.

한편, 본 실시예에서는 본 발명의 스캐너가 신발 제작를 위해 발을 스캐닝하는 용도로 예시하였다. 그러나, 본 발명의 스캐너가 반드시 발의 스캐닝 용도로 국한되는 것은 아니고, 입체물 모두에 적용될 수 있음은 물론이다.In the present embodiment, the scanner of the present invention is exemplified for the purpose of scanning a foot for shoe manufacturing. However, the scanner of the present invention is not necessarily limited to the scanning purpose of the foot, but can be applied to all three-dimensional objects.

전술한 바와 같이 본 발명에 따르면, 스캐닝 동작이 외부와 완전 차단된 상태에서 실시되므로, 외부 노이즈에 의해 촬영 영상이 왜곡되는 현상이 방지된다.As described above, according to the present invention, since the scanning operation is performed in a state completely blocked from the outside, the phenomenon in which the captured image is distorted by external noise is prevented.

또한, 하부 카메라는 투영경에 투영된 화상을 촬영하게 되므로, 투영경보다 높은 위치에 하부를 향해 배치될 수가 있게 되어, 스캐너 전체의 높이를 낮출 수가 있게 된다.In addition, since the lower camera captures an image projected on the projection mirror, the lower camera can be disposed downward at a position higher than the projection mirror, thereby lowering the height of the entire scanner.

아울러, 상부 및 하부 카메라가 각기 2대씩 배치되면서 안쪽으로 경사지게 배치되므로써, 입체물의 전단과 후단에 대한 시야각이 확보되어, 입체물의 전단과 후단을 정확하게 촬영할 수가 있게 된다.In addition, since the upper and lower cameras are disposed inclined inward while two are disposed, respectively, the viewing angles of the front and rear ends of the three-dimensional object are secured, so that the front and rear ends of the three-dimensional object can be accurately photographed.                    

상기에서는 본 발명의 바람직한 실시예에 따른 입체물 스캐너에 대해서 설명 및 도시하였으나 본 발명은 전술한 실시예에 의해 한정되지 않고 하기의 특허청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 본 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양하게 변경 실시할 수 있음을 이해할 수 있을 것이다.In the above, the three-dimensional scanner according to a preferred embodiment of the present invention has been described and illustrated, but the present invention is not limited to the above-described embodiments, and the present invention belongs without departing from the gist of the present invention as claimed in the following claims. Anyone with ordinary knowledge in the field can understand that various changes can be made.
